CHICAGO (CBS) — The reward for information leading to an arrest in the murders of two teenage girls in northwest Indiana has nearly doubled, thanks to donations from former Colts punter Pat McAfee and owner Jim Irsay.

McAfee and Irsay have put up nearly $97,000, bringing the total reward money to $200,000. The reward had reached $103,360 on Tuesday, thanks to donations from the public.

Police said they have received more than 9,000 tips in the murders of 14-year-old Liberty German and 13-year-old Abigail Williams.
